title: New risk factors for coronary heart disease in Asia.
abstract: The increasing prevalence of traditional atherosclerotic risk factors have been documented in Asia but the real impact on prevalence of coronary heart disease (CHD) remains unclear. Smoking, hypertension, hypercholesterolaemia, diabetes mellitus and obesity are present in only 50% of CHD. In community studies of Chinese in Hong Kong and southern mainland-China, aging, smoking and hypercholesterolaemia were found to have a less impact on endothelial function in the Chinese compared with Caucasians in London and Sydney. As endothelial dysfunction is an early event in atherogenesis, there will be a strong need to search for newer risk factors for CHD in Asia, which may become more important in many Asian countries now in the process of modernization. Recently, heterozygous hyperhomocysteinaemia (with or without folate deficiency) was found to be an independent risk factor for arterial endothelial dysfunction, and hyperhomocysteinaemia in association with smoking was a significant risk factor for premature coronary heart disease in Hong Kong Chinese. Other newer factors which have emerged include folate deficiency, low HDL-cholesterol, insulin resistance, abdominal obesity, Methylene-tetrahydrofolate Reductase and Angiotensin Converting Enzyme gene polymorphism.
